    Electrical Issue Genesis

    Hey everyone, I traded an old rifle for a project 2001 Polaris Genesis (carb). When I connect the battery, it turns over just fine, but I'm not getting any spark. Also the MFD doesn't light up other than a red light at the top that flashes sometimes. On top of that, the bilge and reverse are not functioning even though they look clean. The ski was only freshwater used and it looks pretty clean on the inside. I checked the fuses in the box as well as it has a new ignition. Could all this be caused by a bad MFD? Or does it sound like something has lost its connection somewhere down the line? Any advice helps. I checked the forum for hours and could not find anything relating to the combination of things that aren't functioning. Thank you.

    Welcome

    Does the bilge pump run if the Bilge button on handlebar is pressed?

    Tip: These red engine carb ignitions require a really strong battery or they will not spark. Monitor battery voltage while cranking. Voltage must stay above 10.6 volts while cranking, or no spark.

    Hold Bilge button down, and try starting engine.

    Note: The Bilge button forces battery power to the ignition, and to the electric reverse system (and to the bilge pump).

    The MFI display can be bypassed and still allow the engine to crank. Search on here for how to bypass the MFI display security function.

    -The bilge does not respond when button is pressed.

    -The battery is the one off my Yamaha VXR which is new and cranks the VXR to running almost instantly.

    -When I hold the bilge button down and try to start the engine nothing different happens

    -Also another note is that without the kill switch in, the engine will still turn over.

    -I will try the bypass once I can find some copper wire.

    Another Update:

    -MFD is actually somewhat working. It's just extremely dim.

    -The reverse servo works when the bilge button is first held down and then forward/reverse arrows are pressed. Although the guage for FWD/REV on the MFD wacks out when used.

    -MFD displayed 11.9 Volts

    Yet another update:

    When I crank the engine the MFD is only displaying 8-9 volts. After stopping it soars back up to 11.9.

    Have looked inside the electrical box?
    Look for signs of water, corrosion, damage wires, etc.

    Pay particular attention to the black wires and everything related to 'grounding'.

    The entire electrical box is grounded via a single thin black wire that runs to the stator mount, inside the flywheel housing.

    I forget whether there is another thin black wire on the same engine bolt as the heavy black battery cable. THAT ground bolt connection must be clean and solid.

    As you can see it looks pretty clean in the electrical box. Did not find any signs of prolonged moisture exposure. I'll check the grounds next.

    The grounds all have strong connections visually, no rust and directly bolted to metal surfaces.

    Disconnect black battery cable from the negative post at battery.

    Use digital ohm meter to confirm zero ohms from electrical box black wires (check each end of each black wire) to engine case metal.
    Also check for zero ohms from electrical box to the disconnected end of the heavy black battery cable.

    Unplug MFI display and check for zero ohms from black wire at Deutsch connector back to engine case.
    Do the same for the power wire at display plug, back to battery positive cable.

    Check that each color coded wire on the terminal board is actually on the terminal marked for that wire color.
    And that no terminals are bent over or touching another.

    Note that there MAY be a terminal label discrepancy for Grey vs. Tan wires.
